big subtitles(for commercials, or market/restaurant logos)

At this point minecraft only have signs with pretty small letters, and banners(which cannot be seen in a far distance), so i think it woud be pretty cool if we have that feautre, they coud work as block like letter blocks(whick contain letters from A-Z,and it would have a different section in the inventory), or they coud work as the paintings but you coud see them in a far distance.
